Lack of outermost margin with smaller viewport - html

I have a <div id="wrapper"></div>​ with
#wrapper {
height: 300px;
margin: 10px;
position: absolute;
top: 0;
left: 0;
width: 400px;
}​
When I resize the viewport so that horizontal scrollbars appear, the right margin disappears; I can only scroll as far right at the element's content, but I want the margin to be present on all sides. It also happens to the left margin if right: 0; is applied, and to the bottom margin if the viewport is made shorter. Giving wrapper a position: static; (default) makes no difference.
Why is this happening? It doesn't follow normal margin collapse rules. How can I get my margin back? I've tried giving the body padding/margin.. nada.
jsFiddle

Background Info
The default width of the body element is the html width which is also the window width (or iframe width in such a case). The default behavior of a block level element is that the scroll only accounts for the actual element (hence, it doesn't care about the right margin if there is nothing more to display on the right). This causes your right margin issue. (By the way, according to this article, the scroll bars are actually appearing on the html element, not the body.)
For Position: Absolute
By having #wrapper with position: absolute, the body element ends up with zero height. This causes your bottom margin issue in this case.
A solution is to account for the margins like so (see fiddle):
body {
min-height: 320px;
min-width: 420px;
}
This assigns a minimum dimension to the body equal to the width + margins and height + margins of the absolute element.
Now, I'm not sure what you expect to happen if you have right: 0 set, as forcing a left margin to "remain" just ends up causing, in my opinion, a premature scroll bar to activate. See this fiddle.
Regarding Position: Static
The default block level behavior can be changed by forcing a shrink-wrap like behavior on the body element using (see fiddle):
body { display: inline-block; }
Note: that body { float: left; } did not give me the same shrink-wrap behavior (see fiddle).
The inline-block element will account for the margin of its inner elements to determine its own width, which then allows the right margin to work.
The reason the display: inline-block; solution does not work on the #wrapper being position: absolute is because it makes the body have a zero width and height, since the absolute positioning takes that element out of flow and there is nothing left inside body to give it dimension.
The above was currently only tested on IE9.

I'm afraid there's only one simple and quick solution, and that is to create a new div inside the wrapper div.

CSS
#wrapper {
background: black;
height: 300px;
margin: 10px;
position: absolute;
top: 0;
left: 0;
width: 400px;
}
#inwrapper {
background: green;
height: 290px;
margin: 5px auto;
position: relative;
width: 390px;
}
​
HTML:
<div id="wrapper">
<div id="inwrapper">
</div>
</div>
​
And there's your margin.

div with inline-block not resizing

I have two elements, both with display: inline-block, and the parent has white-space: nowrap.
When the screen is resized, the div on the right side don't resize, like this.
I'm trying to make only the blue div resize.
Full source (jsfiddle)
The structure of the html is like this:
<div class="container">
<div class="header">...</div> <!-- red -->
<div class="aside">...</div> <!-- pink -->
<article>...</article> <!-- blue -->
</div>
Relevant css:
* {
box-sizing: border-box;
}
div.container {
margin: 0 auto;
max-width: 40em;
padding: 0;
white-space: nowrap;
}
div.container > * {
white-space: normal;
}
.aside {
display: inline-block;
max-width: 15em;
vertical-align: top;
}
.article {
display: inline-block;
max-width: 25em;
}
Old question, but for the sake of knowledge of anyone who reads this and also has the doubt:
What I've found is that setting position: relative on the .container
and position: absolute on the .article does what I want.
An absolute positioned element is positioned relative to the nearest positioned ancestor, where a positioned element means anything with a position property different to static, the default; if does not found any positioned element, uses the body element.
The absolute positioned elements, if has their width and heigth in auto, resizes to fit its content, and limits the maximun sizes by its positioned ancestor. You can check this putting a short string instead a large one: the element will shrink to the length of text. If you remove the positioning from div.container, the article (if still positioned absolute) will grow (depending on its content) to cover the space between previous element and body width.
And, related to the aforementioned and to add some utility to this delayed answer, a not-very-know bonus: if you define the right and left properties of a absoluted positioned element, and leave the width in auto, the element will cover the horizontal size between the right and left defined. This way you could put something like
article {
background-color: #a0f4ec;
display: inline-block;
position: absolute;
right: 0;
left: 30%;
}
div.aside {
background-color: #faf;
display: inline-block;
max-width: 15em;
width: 30%;
}
This trick also applies in a vertical sense, but with height, top and bottom properties.
There are a few ways to do it.
Method 1:
two divs the same line, one dynamic width, one fixed
Method 2 (negative margins)
http://alistapart.com/article/negativemargins
Unfortunately, Narxx's answers require the divs to be floated. I'm sure that's what you should do if you're building a real site, but in my case, I'm trying not to use it.
What I've found is that setting position: relative on the .container and position: absolute on the .article does what I want.
Simplified fiddle
If anyone can explain why, I'll mark it as an answer.

CSS :: footer alignment and overflow issue

In image above you can footer top border is not aligned with the login box.I want to restrict border width equal to login container width.
and also I dont want x axis to scroll as in image.
To solve overflow issue I used,
html {
overflow:hidden !important;
}
But it does not seems promising to me,
I want something like this ,
footer top border should be aligned with red lines
Fiddle
You are using position: absolute; so you need to use left: 0; for the .google-footer-bar
Demo
.google-footer-bar {
position: absolute;
bottom: 0;
left: 0; /* Add this here */
height: 35px;
width: 100%;
border-top: 1px solid #ebebeb;
overflow: hidden;
}
Also, it will be better if you wrap up the elements, say a maximum 1000px in width and than use margin: auto; to center them, having no wrapper element will just spoil your layout. As far as 100% width element goes, you can use width: 100%; for the container and then nest 1000px; of another child element with margin: auto;, this way your layout will be stable.
You might want to start by removing width and min-width and also height and min-height.

Position absolute right - No scrollbar visible

When I positioning my wrapper absolute and right there is no horizontal scrollbar triggered when I shrink the window.
Example:
http://jsfiddle.net/Ue6aN/
Code:
<div id="wrapper"></div>
#wrapper {
width: 400px;
height: 400px;
position: absolute;
right: 20px;
top: 0px;
border: 1px solid red;
}
If I switch right: 20px; to left: 20px; it's working, but not otherwise. Any idea how to fix that without javascript?
The problem is that there is no content following #wrapper. To get a horizontal scroll there has to be content anchored on the left edge of the document that becomes hidden when the viewport is narrowed, or said content exceeds the viewport width. Since #wrapper is floating right, that's impossible because it has no left-side anchor point. :after makes it work though.
#wrapper { float:right ... }
body:after {
clear:right;
content:' ';
display:block;
height:1px;
min-width:420px
}
The CSS above adds a space after the content of body, which is #wrapper. That space is at least the width of #wrapper's box model, but has no float, and is anchored to the left edge of the viewport. So... as soon as its far right edge is hidden, the horizontal scrolling is triggered; thus giving the illusion that #wrapper is causing the scroll event.
The fiddle: http://jsfiddle.net/jg3nH/
Using float right would be more logical to me but you need to absolute position you could set the width or min-width of the containing element.
body {
position: relative;
height: 400px; //needs to be at least 1px
width: 100%;
min-width: 422px; // the width you'd like to horizontal scrollbar to appear
}

Keeping margin around div with 100% height

The final ancestor div in my page needs a margin on all four sides, to give it a panel effect. Here is my code:
CSS:
html, body {
height: 100%;
}
#wrapper {
width: 100%;
height: 100%;
}
#bibletree {
width: 20%;
float: left;
height: 100%;
}
.inner { /*this is the div that I need a margin around, so it is by 10px of the #bibletree div on all sides, including the bottom.*/
overflow: auto;
}
HTML:
<div id="wrapper">
<div id="bibletree">
<div class="inner">my content here, both short and long</div>
</div>
</div>
As you probably guessed, there is a lot more going on here than what is written. I have several columns with divs that all need this margin for the panel effect on the .inner div. Thanks for any help.
BTW, I have tried absolute positioning and it only positions based on the window, not on the parent element, even if I set the parent to position: relative.
If you set .inner to width 100% and add a margin, it will be wider than its container. You can set a padding or a border instead. For example, you can add a white or transparent border of 10px.
Another option is to make #bibletree position relative, then make .inner position absolute and specify top, bottom, right and left:
.inner {
bottom: 10px;
top: 10px;
left: 10px;
right: 10px;
position: absolute;
}
This will make it the same size as #bibletree, minus 10px on every side.
Margin:10px is working right?? you need not no specify the width for inner div, as div is already has block option. check here updated demo http://jsfiddle.net/QShRZ/5/

Place a footer with Content positioned as absolute

I have a wrapper class that contains all the content on the web page. the problem is if the content is absolutely placed, it eats my footer. I have to place the content as absolute positioned.
It seems like the footer doesnot recognize that the content is absolute. Heres my code
<style>
* {
margin: 0;
}
html, body {
height: 100%;
}
.wrapper {
min-height: 100%;
height: auto !important;
height: 100%;
margin: 0 auto -4em;
}
.footer, .push {
height: 4em;
}
</style>
</head>
<body>
<div class="wrapper">
<img src="activity/Chrysanthemum.jpg" style="z-index: 1; position:absolute; width: 420px; height: 400px; left: 100px;top:260px; ">
<div class="push">
</div>
</div>
<div class="footer" >copyrights</div>
</body>
If I change the image style by removing the position:absolute property , everything looks normal. so my question is how can we place the footer at the bottom with absolute positioned contents?
Updated answer, regarding comment.
As I mentioned at my previous answer, this effect cannot be achieved using pure CSS. So, I will show the JavaScript approach. Add relevant IDs (see Fiddle), and add the following code at the end of your body. This code snippet will resize your wrapper when necessary.Note: When the page is smaller than the window's height, the page wrapper will still take the full height, because it's not possible to distinguish a height change by an absolutely positioned element.
<script>
(function(){
var wrapper = document.getElementById("wrapper");
var height = document.documentElement.scrollHeight;
wrapper.style.height = height + "px";
})();
</script>
Previous answer:
The issue is caused by the fact that absolutely-positioned elements do not affect the height/width of their parent.
To fix your code, apply the following CSS (only showing relevant CSS, updated postfixed by descriptive comments). Fiddle: http://jsfiddle.net/4ja2V/
html, body {
height: 100%;
width: 100%;
padding: 0; /* Get rid off the padding */
}
.wrapper {
position: relative; /* Necessary to properly deal with absolutely positioned
child elements. */
height: 100%;
margin: 0 auto 4em; /* So that the content is visible when scrolled down*/
}
.footer {
height: 4em;
position: fixed; /* Positions your footer at a fixed position in the window*/
bottom: 0; /* At the bottom of the window*/
}
You were using a negative bottom-margin for .wrapper, which caused the element to "eat" the footer. When you're using absolutely poisitioned inner elements, there's no reliable pure-CSS method to get the real width/height of the .wrapper element. Hence the appearance of position:fixed.
The footer is defined to have a height of 4em. Because the footer is positioned at a fixed position (ie, the element won't move when scrolling down), it's necessary to apply an additional margin at the bottom of the wrapper element.
give your footer a fixed hight and then in your absolute class, do
bottom: heightOfYourFooter + 5px;
